A cup of green tea comes with about 100mg of EGCG, which is 8 cups of green tea.

It is hard to come to a definite conclusion based on lab research, but numerous experts are stating 300mg of EGCG is a proper amount to take on a daily basis. There are actually dependable lab results with the dose of 300mg against cancer cells and weight reduction.

Due to the increasing interest in green tea as a weight loss aid, additional laboratory tests will likely be conducted. As for now, 300mg seems to be a safe amount for both EGCG and caffeine.
